I "recently" got 3 betta fish, a veil tail, a double tail, and a elephant ear. All males of course. I got them around mid June.. For the past few days (and most likely longer) I've noticed that my elephant ear male's body does this weird curve thing. It's always to the same side (As far as I've noticed anyways) sometimes it's a U and other times is an S curve. I've read other threads but none were helpful to me at all.. I'm starting to get a little worried.. After my double tail male had issues (Im pretty sure he was constapated) I stop feeding them so much, because I was infact over feeding, I've only been feeding each of them 2-3 pellets per day, only once a day.. I've been doing this for about a week.. My double tail male is fine and made his first bubble nest..but my elephant ear male hasn't yet.. there's bubbles but.. maybe his bowl isn't big enough. That's another thing. My mother refused to buy tanks and said to "use what we have at home" so my elephant ear male is in the smallest shallowest little bowl compared to my other two fish :( I've still been trying to find another bowl for him at stores but I have been unsuccessful. None of my fish have heaters as I've heard is highly recommended. It's summer here and my house gets around 80-90 degrees in the afternoon (I'm not exaggerating) I've notice some of my elephant ear males water has evaporated .. I change their water once a week, the elephant ear males more often since his bowl is smaller.. He's pooping regularly, and he eats.. I can't really tell if he sits at the bottom of the bowl or not.. since it's not much of a "dive" ... I'm terribly sorry for the long post, I'm just trying to provide as much info as possible to help ..
